Rockridge Quarry supplied all the Rip-Rap for these Corps of Engineers Projects:

• Blue River Channel Modifications-Over 200,000 tons of Rockfill and over 50,000 tons of 15” to 24” Rip Rap supplied to this project.
• Birmingham Levee
• Riverside Quindaro Levee-Over 130,000 tons of Rockfill supplied by Rockridge for this project.
• Rockridge Quarry supplied all the material, which included 2-9 ton stones and 9-16 ton stones (many of these were as big as cars and required special equipment to transport and place them) for the Johnson County Water District #1 in Kansas City, Kansas to help stabilize the Jetty located by the power plant. Lexaco was the contractor for this project.

Rockridge Quarry is approved to supply all Rock and Rip Rap for the following Drainage Districts by the Corps of Engineers.

• Fairfax Drainage District
• Kaw River Valley Drainage Districts.

 To be an approved supplier for the Corps of Engineers, stringent testing is performed by the Corps on the rock layers at Rockridge Quarry.

 Once the rock is proved to be of excellent quality it may be used on Corps of Engineers Projects and for drainage districts that are required to use rock approved by the Corps of Engineers.
